Spiritualism - The Fox Sisters by Donna Zuckerbrot - DVD

This story began on the night of March 31, 1848 in an isolated
farmhouse in upstate New York. Two little girls and their horrified
parents seemed to communicate with the dead. In the months and years
that followed, the events in this small community grew to become far
more than a simple ghost story. They became the starting point for a
new mass movement referred to as modern spiritualism that influenced
tens of thousands of people for the remainder of the nineteenth
century.
